YAP: Yet Another Partial-Wave-Analysis Toolkit — •Paolo Di Giglio, Daniel Greenwald, and Johannes Rauch — TUM, Munich, Germany

We will present a new C++ library: YAP, the Yet Another Partial-wave-analysis toolkit. The library calculates amplitudes for multibody particle decays in several model frameworks. It is intended for the analysis of spin-0 heavy mesons, but is programmed with the flexibility to handle other decays. The library implements isobar decompositions, K-matrix formalism, and model-independent approaches for mass-dependent amplitudes; and both Wigner rotation and Zemach (for 3 particles) formalism for spin amplitudes. We will introduce the software and give example use cases.
